Some 65 million years ago, an asteroid the size of a small city hit the Yucatan Peninsula in what is now Mexico. The impact devastated Earth, generating huge tsunamis, massive wildfires and rapidly heating the atmosphere. It triggered earthquakes and volcanic activity and then cooled the world as smoke and dust blanketed the planet.

This impact changed the future of the Earth, triggering the sequence of events that led to the extinction of the dinosaurs, the rise of mammals and ultimately the domination of humans.

Now Christopher House and pals at Penn State Astrobiology Research Center in University Park, say this event may have had an equally profound influence on other parts of the Solar System.

These guys have calculated the number of rocks ejected into space in this collision that would have been capable of carrying life and protecting it in space. They say that significant numbers of these rocks would have made the journey to Mars and Venus but also to Jupiter and Saturn. In particular, they say these rocks would probably have travelled to moons such as Europa, Callisto and Titan, where astrobiologists believe that conditions are ripe for life.

About Me

Actually, I am a Rocket Scientist.
Also hormonally odd (my blood has 46xy chromosomes anyway) and for most of my life, I looked male, and lived as one, trying to be the best Man a Gal could be. Anyway, in May 2005 that started changing naturally for reasons still unclear, and I'm now Zoe, not Alan : happier and more relaxed not to have to pretend any more.
UPDATE - reason now identified as the 3BHSD form of CAH.

Reviews

This blog, written by a rocket scientist, is a fascinating collection of information, both personal and scientific, regarding intersex, transsexualism and related psychosocial and psychosexual issues....It is erudite and heartfelt. Just read the posts about the passport issue. You won't know whether to laugh, weep or crawl into a ball and rock gently in a corner - an amazing person.- David---The reason I so appreciate bright, perceptive people - as opposed to ideologues whose intelligence does little to illuminate - is that they manage to both instruct and learn with a certain grace. Among such rarities in the transblogosphere is Zoe, whose direct speech and clear humanity always make her worth reading, even if one doesn’t always agree with her every conclusion.- Val---The following is a request for permission to archive your A.E.Brain blog site which we have wanted to do for several years...The Library has traditionally collected items in print, but it is also committed to preserving electronic publications of lasting cultural value....Since (1996) we have been identifying online publications and archiving those that we consider have national significance....We would like to include A.E.Brain blog site in the PANDORA Archive...-Australian National Library
